Call me stupid, but... I just now noticed that some doors have cashiers/tellers and some don't. When someone drops a bag of money on a manned window it's worth 1000 bonus points.
Manned windows also seem to attract more bandits than unmanned windows.
The number of points received for a single bag of money increase according to the number of bags previously received on that window (200, 400, 600, 800 and then 1000).
So the best strategy would be to spend most of the time around the same windows (preferably around one with a teller) to increase the number of bonus and high value deposits.
Gosh, I spent so much time playing this game and never analyzed it like that. You guys are ruining the magic to me
